Because that is the only color that the bull sees.

 

Because that is the only color that the bull sees. Real Answer It's traditional. Cattle are color blind. It is the motion of the cape that gets the bull's attention, not the color. A black or blue cape would work just as well. Ref: http://www.vet.utk.edu/
